A unique cooling method that cools via the nasal cavity


The QuickCool® SYSTEM regulates the body temperature of patients at risk of oxygen deprivation due to illness, accident or trauma. The cooling method is unique, as the system cools via the body’s built-in heat exchanger: the nasal cavity.

As the nasal cavity is close to the brain, the cooling process to protect the brain is rapidly initiated. Medical staff can work and carry out treatment, such as defibrillation or chest compression, unhindered by the cooling system.

The QuickCool® SYSTEM ensures stable, high-precision temperature control for the patient. The cooling chain remains unbroken from the moment the target temperature is reached to the moment cooling is no longer required.

There is a built-in automatic function to ensure a return to normal body temperature (normothermia) when the cooling treatment ceases, which reduces the risk of fever peaks.

Unbroken cooling chain


The system offers an unbroken cooling chain – from application in an emergency care or intensive care unit to the end of the cooling treatment, possibly at another medical care unit.



The unit is hung on the patient’s bed and automatically switches to battery power when no mains power is available. This means secure temperature control is also provided during transfer and transport of the patient.

Easy to use


The QuickCool® SYSTEM is easy to use – medical staff require only a short introduction before using the system. 

Safe usage


The treatment is non-invasive and does not irritate blood vessels or affect the patient’s circulatory system.

Balloon catheters


The balloon catheters, made of a very thin, soft and supple material, are mounted on flexible, thin tubes, which make it easy to introduce them into the nasal cavity.


  • What does the QuickCool® SYSTEM do?

    The system regulates the body temperature of patients at risk from oxygen deprivation due to illness, accident or trauma. The cooling method is unique, as the system cools via the body’s own heat exchanger, the nasal cavity, which is very close to what needs to be protected – the brain.

    This system ensures there is an unbroken cooling chain from the moment the target temperature is reached until the moment cooling is no longer required.

  • Why is it important to cool down patients?

    Every 17 minutes someone in Sweden has a stroke, and every year over 10 000 people suffer a cardiac arrest. This is often catastrophic for the brain, which depends on a supply of oxygenated blood. If there is brain ischemia – insufficient blood supply to the brain – the brain suffers oxygen deprivation. This causes cell death in the brain and entails a considerable risk of serious and permanent brain damage.

    Cooling the brain down slows this process and the affected patient has a greater chance of surviving and recovering.  Cooling can also be used for intensive care patients with fever.

  • What temperature is recommended?

    The Targeted Temperature Management (TTM) guidelines recommend that cardiac arrest patients are maintained in the temperature range 32°C to 36°C during a treatment period of 24 to 48 hours, but treatment periods of 72 hours are also possible.

    There are currently no international guidelines regarding stroke and fever, however clinical studies are being conducted in these areas of application.

  • Does cooling via the nose cavity give you a “brain freeze”?

    Brain freeze arises when you eat something cold very fast. One theory is that the nerves in the roof of the mouth send signals about the chill to the brain, which increases the blood supply to compensate. The overheating that results causes the pain and this comes via the roof of the mouth, not via the nose.

  • Can the patient breathe through the nose?

    No, it is not possible to breathe through the nose if you are being cooled down via balloon catheters, but the patient can breathe through the mouth without problem. If the nasal cavity is occupied, this is not a clinical problem.

  • Is it possible to intubate at the same time?

    Yes, this is possible, as intubation is introduced orally via the windpipe to create a secure airway. The QuickCool® SYSTEM does not affect this routine.

  • Is it possible to use a nasogastric tube?

    Yes, a nasogastric tube, for providing nutrients, liquid foods or medicine, may be placed parallel to the balloon catheter in the nose. The tube should be placed close to the nasal septum in order to minimize the risk of reducing the cooling capacity.

  • Is it possible to use an oxygen mask?

    Yes, an oxygen mask is placed over the nose and mouth in most cases. As the balloon catheters are placed inside the nose and the connections only consist of thin tubes, the mask’s function is not affected.

    Note: Oxygen tubes made to deliver oxygen via the nose cannot be used with balloon catheters as the QuickCool® SYSTEM does not allow breathing via the nose.

  • Are EEG measurements disturbed by the QuickCool® SYSTEM?

    In EEG, electrodes are attached to the head to measure the brain’s electrical activity in order to obtain a basis for decisions concerning continued treatment. EEG can be carried out while using the QuickCool® SYSTEM.
